      George,
      
          We run Dovecot with Outlook, and have had similar problems
      when Outlook is operating in "Offline Mode". When you're in
      offline mode, doing any folder-level operations, such as Copy,
      Create, Rename, Move, Delete, etc. causes problems with the
      mailbox. The end result is that you could lose e-mails and entire
      folders that were involved in the offline operation.
      
          How we have fixed this in the past, what we have done is:
      
        - Do an Outlook "export" of the entire contents of the IMAP
          account into a ".pst" file. (This saves the e-mails that may
          be at-risk of being lost.)
- Delete the IMAP account in Outlook, which includes the
          ".ost" file.
 
- Delete the IMAP account on the Dovecot server
- Reconfigure the IMAP account in Outlook
- Restore the IMAP contents from the ".pst" file in step #1.
- Educate the user about not doing folder-level operations
          while in offline mode.
 
Hope this helps...
    
    
    
    Thanks,
    
    that means that outlook is useless as an Imap client then . This is
    the whole idea behind
    imap, to be able to do work while off-line and sync changes when
    on-line or I get it wrong ?
    
    thanks anyway
